First List:HQ:
Reclusiarch is a great choice remove the jump pack and put him and DC in a Rhino.

Troops:
Remove JP's from DC (JP DC are just too expensive for what they do...and too dangerous with the Rage rule.)Bump up to 9 DC, and I would also remove a Pwr Wpn or 2 and have some abalative bodies for casualties.

Dred is a good build and very deadly against Hordes.

Give Assault Squads a P. Fists when you are 10 man strong, you won't regret it. If you have a 5-man size, a Pwr Swrd is the better choice.

Fast Attack & Heavy Support:
With the points saved from dropping equipment from DC give all your vehicles extra armor and your good to go.

Second List:HQ:
Librarians in BA armies are mostly taken for a support role(Shield of Sang, Psychic Hood). They are too fragile to get heavy into assaults, so I wouldn't waste the points on Epistolary. Good list of spells are Shield of Sang and Blood Lance.

Elites:
Drop the Sang. Guard they are a points sink, and not all that effective.

Priest is good, keep them cheap and out of combat.

Good build for the Dred.

Troops:
Assault Squads - Drop the Pwr Wpn and give them a P. Fist, also give them a 2nd Meltagun.
